SHUTTLE AND METHOD 0F MAKING SAME.

Application filed March 4, 1924. Serial No. 696,736.

To all whom t may concern.'

Be it known that I, VVILFRED J. GLADUE, a citizen of the United States, residing at lVoonsoclret, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Shuttles and Methods of Making* Same, of which the following is a specification.

rI`his invention relates to certain new` and useful improvements in shuttles and method of making same, and the primary object thereof is to provide a shuttle the body'of which is fo-rmed of fiber, thereby to economize in the cost of production, both as concerns the cost of material and the manufacture.

A further object of the invention is to provide a method of making the shuttles which can be easily and expeditiously practised.

Still further, the invention has for its object the provision of novel caps for the shuttle ends and means for attaching same in position.

The invention has still further and otherl objects, which will be later set forth and manifestedin the course of the following description.

In the drawings Figure 1, is a top plan view of the shuttle, partly broken away, constructed in accordance with the present invention;

Figure 2, is a` side elevation of Figure 1;

Figure 3, is a top plan view of one of the end castings;

Figure 4, is a side elevation of Figure 3;

Figure 5, is an end elevation of Figure 4,

Figure 6, is a section on line 6-6 of Figure 1,

Figure 7, is a top plan view of the other end casting;

Figure 8, is a side elevation of Figure 7,

Figure 9, is an end elevation of Figure 8,

Figure 10, is a side elevation of one of the end caps, and

Figure 11, is an end elevation of Figure 10.

In proceeding in accordance with the resent invention, atube of fiber in what is generally termed .its green7 or wet state is employed. A form is introduced into the tube interior, which includes end members of somewhat truncated cone formation, the end members being connected by a series of central or intermediate form members, t-he end and central or intermediate form members having mitered `ioints. The outer ends or tips of the end form members have reduced or depressed portions corresponding in form to that of the metallic tips or caps 12, which latter are illustrated in Figures 10 and 1l of the drawings. The form composed of the end and intermediate members has an external shape corresponding to that which the finished shuttles is to possess. The green fiber is neXt subjected to pressure so as to compress or shape and cause same to conform to the shape of the form, which step results, in the shaping of the fiber ends with inwardly offset parts forming depressed portions indicated at 6 in the drawings. The fiber is now dried or baked so as to cause same to become hart and maintain the shape imparted thereto by the form, following which the central top portion of the fiber is removed, as by cutting down to the form, to provide the usual bobbin-receiving cavity or chamber 7.

The several sect-ions of the form are now removed and castings 8 and 8 positioned in the ends of the fiber body, the castings having cut-out end portions 9 and 9 which receive the depressed portions 6 occurring at the ends of the fiber body. These castings may be made of aluminum or other metal and are provided with bores 10 the latter receiving metal threaded shanlrs 11 of the end caps 12. Nuts 13 are applied to the Shanks 11 and are driven thereon so as to effect firm anchorage of the caps to the fiber body. The wings 14 of the end caps have their tips 15 deflected inwardly so as to be embedded in the liber and be firmly anchored thereto. From the foregoing it will be noted that the ends of the fiber body are strengthened and reinforced both interiorly and exteriorly thereof, and are held against any tendency to move outwardly by the end caps which clamp the fiber tube ends aga-inst the interior castings.

The castings and end caps are additionally secured in place by cement.

The final step resides in applying linings or sections of bakelite or equivalent material 16, which latter are sprung into position in the fiber body and are cemented to the side walls thereof.

The castings may be of any type desired to accommodate any desired type of bobbin mounting and the usual or any preferred form of threading and delivery eyes.

Having thus described my invention what l claim .as new and desire tosecureby Letters .Patent is i' l. In a shuttle, a tubular liber .bodyhaw ing tapered ends formedrwith inwardly oil'- set parts forming eXternal depressions, castings in the ends of Ethe body `having depressed parts to receive the said offset parts and having axial bores, end `caps engaged over the ends of the fiber body and having wings .received .in .said external: depressions,

.the ,tips of the wings `being deflected in- .warclly and embeddedin thebodysaid caps havingthreaded shanksreceived in .theca'std ing bores, nuts in fthe castings enga-ged `with .the Shanks tto draw .the .caps andcastings together, and linings lnvthe bodysecured to the sides thereof.4

l2. VIn ashuttle, 4a tubularliber body having .tapered ends formed with inwardlyY oil"- set parts forming external. depressions, cast ings .iin the ,ends of: the ,body Lhavingdepressed ,pa-rtsto receive the said Yoffset parts and having axial. bores, endcapswengaged.

,said ,caps having ,threaded Shanks received intheQcastngibores, and nuts on the shanks .to draw the caps andcastingstogether.

In a. shuttle, ,a tubular. .liber body having 4,tapered ends, astings, inl the` endsof the body, end caps `-litted over Asaid ltapered ends ,ofthe body, and Vlmeans .to .secure the ,'aps and castings together. ,and with parts of fthe' ends 'of the" ibody clamped .therebetween 4L. ln a shuttle, a vtubular-iberbody having,

itapered 4ends, .castiiigsu'in the ends of lthe body, end caps fitted over .said taperedvends of .the body, means to secure. the ,caps and ,castings to-getherland'.Withfpants o the ends of thebody clamped therebetween, andlining members 4secured to theijlnner side faces 4oi" the body.

16. The hereindescribel method of'making i shuttlesfwhich,consists in placing a Vform on linally .in -securing lining meinbersqto the inner side faces of the stock.
